The word(s) "when" appears 1006 time(s) in 918 verse(s) in Quran in Muhammad Pickthal translation.

(191) No plea had they, when Our terror came unto them, save that they said: Lo! We were wrong-doers.

(192) Then verily We shall narrate unto them (the event) with knowledge, for We were not absent (when it came to pass).

(193) He said: What hindered thee that thou didst not fall prostrate when I bade thee? (Iblis) said: I am better than him. Thou createdst me of fire while him Thou didst create of mud.

(194) He said: Reprieve me till the day when they are raised (from the dead).

(195) And (unto man): O Adam! Dwell thou and thy wife in the Garden and eat from whence ye will, but come not nigh this tree lest ye become wrong-doers.

(196) Thus did he lead them on with guile. And when they tasted of the tree their shame was manifest to them and they began to hide (by heaping) on themselves some of the leaves of the Garden. And their Lord called them, (saying): Did I not forbid you from that tree and tell you: Lo! Satan is an open enemy to you?

(197) O Children of Adam! Let not Satan seduce you as he caused your (first) parents to go forth from the Garden and tore off from them their robe (of innocence) that he might manifest their shame to them. Lo! he seeth you, he and his tribe, from whence ye see him not. Lo! We have made the devils protecting friends for those who believe not.

(198) And when they do some lewdness they say: We found our fathers doing it and Allah hath enjoined it on us. Say: Allah, verily, enjoineth not lewdness. Tell ye concerning Allah that which ye know not?

(199) And every nation hath its term, and when its term cometh, they cannot put it off an hour nor yet advance (it).

(200) O Children of Adam! when messengers of your own come unto you who narrate unto you My revelations, then whosoever refraineth from evil and amendeth - there shall no fear come upon them neither shall they grieve.
